| Outline of Final Research Achievements |
We conducted the research for 1) Elucidating the actual situation of risks caused by abandonment of satoyama forests and artificial forests, 2) modeling risks and extracting high-risk areas, and 3) drawing a scenario of withdrawal from satoyama forest and artificial forest. As a result, 1) the windthow risk in artificial forests rises more greatly in places with high risk even in natural forests, 2) big male bear with large body sizes appear on low popularity agricultural land adjacent to the forest and use corn. 3) as a means to reduce both risks of artificial forests and satoyama forests, there is the conversion of artificial forests into mixed forest. Conversion of the old stands into mixed forests which is located on the protrusions on the slope is the most effective for reducing windthrow risks. We proposed other management methods for effective risk mitigation.
